The size of the jump at each point is equal to the probability at that point. For, example, at point $x=1$, the CDF jumps from $\frac{1}{4}$ to $\frac{3}{4}$. The size of the jump here is $\frac{3}{4}-\frac{1}{4}=\frac{1}{2}$ which is equal to $P_X(1)$. Also, note that the open and closed circles at point $x=1$ indicate that $F_X(1)=\frac{3}{4}$ and not $\frac{1}{4}$. Fig. 3. 3 - CDF for Example 3. 9. In general, let $X$ be a discrete random variable with range $R_X=\{x_1, x_2, x_3,... \}$, such that $x_1 < x_2 < x_3 <... $ Here, for simplicity, we assume that the range $R_X$ is bounded from below, i. e., $x_1$ is the smallest value in $R_X$. If this is not the case then $F_X(x)$ approaches zero as $x \rightarrow -\infty$ rather than hitting zero. Figure 3. 4 shows the general form of the CDF, $F_X(x)$, for such a random variable. We see that the CDF is in the form of a staircase. In particular, note that the CDF starts at $0$; i. e., $F_X(-\infty)=0$. Then, it jumps at each point in the range.
